I have to assume that this gag would make sense to big “Flash” fans, but what good does that do me? Based on what I know thus far, Batton’s gym closed during the pandemic, so he wandered over to Atomik Komix HQ, where, as fate would have it, they had a treadmill he could use. And no one at AK seems to mind or finds this peculiar in any way. On the contrary, they actually seem fine with it, engaging in wry banter with Batton as opposed to saying something like “what the f*ck are you doing?” or something like that.
And if his gym closed due to the pandemic, is it wise for him to be wheezing all over a bunch of people (three of them elderly, no less) he doesn’t even really know? And what about the potential liability issues here? If Batton snaps a tibia or dies on that thing, the cops and lawyers will definitely be asking questions about AK’s incredibly lax security, and those questions won’t be wry.
